Nitration of aromatics with nitrogen oxides in trifluoroacetic acid

Patent ·
OSTI ID:6163872
In a process for nitrating aromatics using lower valent nitrating agents in trifluoroacetic acid, the product yield of nitroarenes can be significantly increased by maintaining an excess of nitrating agent over the stoichiometric amount during the reaction.
